What It Actually Is
Muira Puama (Ptychopetalum olacoides) is a shrub from the Amazon rainforest, with bark and root traditionally used in Brazilian folk medicine, sometimes referred to as 'potency wood.'
What Research Generally Shows
Research on muira puama is limited compared to more mainstream botanicals, consisting mostly of traditional use records and a small number of preliminary studies.
The Honest Gap
VigorBoost's muira puama amount isn't disclosed within the 82mg blend, and the overall research base remains thin.
